I have a 02 C320 and my turn signal on the passenger side quit working. Not the bulb....switched out one side to the other and they both work on the drivers side. I have no idea what is going on. Anybody else have this problem??????? Any info would be great

 

are you talking about the turn signal up front ? If up front take out the bulb socket and inspect the contacts on the bulb socket. sometimes these get over heated or some corrsion on them. use some fine sand paper and scuff off the corrsion and clean the contacts. and you might just want
to pry the contacts out just a littel bit to make sure they make good contact with the inside of the headlamp housing. give it shot maybe it will work.

 

Yea its the front bulb that fits into the headlight assembly. Ill try that today and see what happens.

 

Well good news! It worked! Thanks Tronics, the socket that the bulb fits into had a tiny bit of corrosion on one of the contacts that connects the socket that the bulb fits in and the contact on the headlight assembly. I just never thought it would have been a problem cosidering how many times I pulled that stupid thing out and put it back in. I also pryed out the connetcions a litttle bit as well. If anybody else has this problem, there wasnt very much corrosion at all on it so dont rule it out at first sight.

 

I'm having the same problem. I have got new bulbs from the mercedes dealership, still not working, any other suggestions?
